I don't have a beach body, nor a desire to go to the pool, but I have done a little sun bathing in private locations. My only advice is be aware that you will end up with tan lines that will be there for the rest of the summer and into the fall. So if you remove your shirt from that day on you will be providing evidence for your adventure. Sun screen will help, and should be used anyway, but the story will be written on your body regardless.
That being said, enjoy!
